[Zope] file upload formular

hi all For our intranet I'm going to improve the file upload. In the past, the workers had to upload their files via the ZMI. They had to add some properties (like author, keyword, etc.). Afterwards some dtml-methods listed the content of the directories by mapping the properties of the documents. I now want to create a html-form which help the people to upload their files. In this form they have to insert the properties and after pressing the submit button, the file should be uploaded into Zope. I'm sure this was done by other users before, but I didn't find something. Any good ideas or code out there? regards sim
